LINGERIE-CLASP.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed April 8, 1919. Serial No. 288,589.

useful improvements in lingerie clasps, and

the primary object of the invention is to provide a clasp which has improved means for gripping the material so as to more effectively and positively hold the same within the clasp, and thereby eliminate the danger of accidental slipping of the clasp and consequent loss thereof, or displacement.

The invention further aims to provide a clasp of this character which can be cheaply and easily produced, and which has clamping points that are formed integral with the clasp without slitting or otherwise altering the body of the clasp by adding extraneous parts thereto.

In the drawings- Figure 1 is a side elevation of the invention.

Fig. 2 is a bottom plan view.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. 4 is a view similar to Fig. 1 of a modified form of the invention, and

Fig. 5 is a section on line 55 of Fig. 4.

In proceeding in accordance with the present invention, a clasp is formed of a strip or length of material having preferably parallel side edges, and embodying a lower member 1, forming the body and a clasp or jaw member 2, the latter being bent over in spaced relation to the lower member 1 and having a curved end 3, which snaps over a correspondingly curved end 4 formed on the member 1, so as to secure the two members in closed or operative position. I

As shown in Figs. 1, 2 and 3 of the drawings, clamping points 5 are formed by bending the metal at the side edges of the member 1, inwardly and upwardly, thereby forming two pairs of clamping points which are each of U-shape in cross section as shown in Fig. 3. The clamps thus provided afl'ord four spaced clamping points, which are located in pairs at spaced points along the length of the member 1, and confront the member 2, so as to effectively grip and clamp the material. In addition the formation of the U-shaped clamps as above described results in the metal being displaced to extend below the bottom face of the member 1, thus providing additional clamping points which engaging the material or garment will act' to prevent shifting of the clasp, as is believed manifest.

In Figs. 4 and5, a slight modification is shown, but one pair of gripping or clamping points being employed, which points are of substantially 'U or somewhat V-shape in cross section, and do not project at the base of the V below the plane of member 1. In this instance the clamping points are located centrally of the length of the member 1, so as to lie opposite to the center of the length of the member 2.

In both forms of the invention, the pairs of points are formed by forcing the metal at the sides of the member inwardly toward the center of the member, thus providing a most economical and simple structure which dispenses with slitting of the metal, and also does not require any special shaping of the member 1, since the parallel straight sides of the latter are preserved.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1. In a clasp having a lower member and an opposing member, a substantially U-- shaped clamp borne by one of said members and formed by bowing the normal side edges of said member inwardly toward each other, said side edges forming the sides of the U and the base of the latter extending below the under face of said member.

2. In a clasp having opposed jaw members, clamping means borne by one of the members and formed by bowing the normal side edge of the member inwardly so as to form a projection facing the other mem-.

ber and disposed intermediate the sides of said member.

3. In a clasp having opposed jaw members, clamping means borne by one of the name to this specification in the presence of members and formed by bowing each of the two subscribing witnesses. opposite side edges of the member inwardly OSCAR R. JOHNSON.
